You can verify what kernels are available to Jupyter by running:

jupyter kernelspec list

If you’ve installed 3.9.1 and its in the search pathway for Jupyter, it should be listed there. You can then choose the kernel at runtime in the top right corner of the notebook. If it doesn’t show up, that’s a longer answer and I would start by reading through this thread.
